Application May 12, 1933, Serial No. 670,679

1 Claim.

This invention relates to improvements in reenforced concrete blocks, particularly blocks to be used for the erection of comparatively large containers or vats.

Vats or large containers for liquids have heretofore been constructed by the use of doublewalled plank forms into which the inner reenforcing bars or rods were placed and embedded into concrete poured into the forms and tamped,

whereafter, upon the removal of the forms the Walls were finished.

This construction has the disadvantage that the vats which were preferably semi-detached and connected with and erected close to the 15 walls of a building had to participate in eventual settling or sinking of the walls of the building or vaults resulting in damage to the vats. In

many of such cases the foundation of the vats gave way under their own weight or the weight 0 of their contents had the tendency to settle further than the floor or walls of the building, and

causing the vat to become leaky. Such leaks could be stopped by providing a new inner lining which however will not prevent further settling of the 5 structure.

It is the purpose of the present invention to provide a ferroconcrete vat or container perfectly detached from any building wall and made from specially constructed tiles of reenforced concrete assembled to form the side walls, the bottom and, if required, the top. Specially constructed tiles are used for the blending of the bottom and the side walls and the formation of the corners. These tiles are formed either with vertical bores or horizontal channels formed by grooves in two adjoining tiles into which the metal reenforcing rods are placed which are then filled with the cement or concrete forming a structure of great strength.

The corner stones are provided with horizontally arranged channels angularly disposed to one another. In the construction of the bottom and top plate-shaped tiles are used which have circumferentially arranged horizontal grooves forming wire channels between two adjoining tiles which are filled with a concrete mixture after the metal reenforcing bars or rods have been placed therein. The tiles forming the transition or blend between bottom and side walls 0 have special form for the formation of the corners as well as for the side Walls.

These and other objects and advantages of my invention will become more fully known as the description thereof proceeds, and will then be specifically defined in the appended claim.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a perspective View of a vat or large container for liquids constructed according to my invention.

Figs. 2 and 3 show concrete blocks used in the construction of the bottom of my vat.

Fig. 4 illustrates another form of block to be used in the construction of the bottom.

Fig. 5 illustrates a modified form of concrete slab to be preferably used for the erection of the side walls of a container when for instance divided.

Fig. 6 is a section on line 6--6 of Figure 5.

Fig. 7 is a sectional view of a corner stone.

Fig. 8 illustrates a section of two blocks used in the construction of the roof.

Fig. 9 illustrates the construction of the side Walls by the slabs (Fig. 5).

As shown, a vat 10 or container for beer, chemicals or the like is constructed from tiles 11 forming the cornerstones with raised ridges on two sides in juxtaposition to which the stones 12 are placed forming the tiles blending the transition between the bottom stones l3, and the tiles 14 forming the side walls.

The entire structure is built or erected upon small concrete slabs or beams 15 to separate the bottom of the vat from the foundation.

Horizontally arranged grooves 16, 17 are arranged on tiles 12, 13 for the reception of the reenforcing metal rods or bars, while the tiles 14 for the erection of the side walls have horizontal upper and lower grooves 18, 19 and vertical grooves or channels 20, 21, the former for the reception of the reenforcing bars 22, 23 and the latter for the insertion of the vertical reenforcing bars 24, which are connected to the reenforcing bars 25 for the bottom tiles 16 as shown in Figure 9.

The top of the vat, if such is desired is formed by series of slabs 26, two tiles of each series being separated allowing the passage of the reenforcing cross bars 27 and longitudinally extending bars 28 located in the grooves 29 of the tiles 26. The ends of these rods or bars are connected with the ends of the vertical bars 24 of the side wall tiles 14 by soldering or the like, as indicated at 30.

In use the tiles are assembled so that their adjoining grooves form channels into which the reenforcing metal bars or rods are placed and which are then filled with concrete or cement mortar whereupon the adjoining ends of the bars are connected by welding or the like.

An inner lining suitable for the purpose may be provided, and if desired a man-hole 31 is arranged of suitable material at a convenient location. It will be evident that the stones or tiles in Figure 5 may be used in any desired length, eventually cut into suitable lengths; The concrete slabs supporting the vat on a floor will provide a space between bottom of the vat and the floor allowing an observation of any leak in the bottom.

It will be understood that I have described and shown the preferred form of tiles and vat as examples only of the many possible constructions thereof in practice, and that I may make such changes in the specific construction of the minor details or in the general arrangement as come within the scope of the appended claim without departure from the spirit or my invention and the principles involved. 7

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

bars and concrete, corner stones having circumferential grooves and arranged in series of two for the reception of ferro-rods or bars in the adjoining grooves, the ends of said bars with the ends of the vertical bars in the side walls connected by welding, and bottom forming stones having horizontal reenforcing bars embedded therein and connected to the vertical reenforcing bars of said side walls.
